BEIRUT, Lebanon — The number of registered Syrian war refugees who have flooded into Lebanon exceeded one million on Thursday, the United Nations said, describing it as a devastating milestone in a humanitarian crisis that has overwhelmed this small country and severely taxed the ability of the government and aid organizations.

Lebanon now has the highest concentration of refugees as a percentage of population in the world, with about one Syrian for every three Lebanese. And new refugees keep coming as the civil war, which by some estimates has left more than 150,000 people dead, grinds into its fourth year. Each day, the United Nations registers 2,500 refugees in Lebanon, equivalent to more than one person per minute.

“The influx of a million refugees would be massive in any country. For Lebanon, a small nation beset by internal difficulties, the impact is staggering,” António Guterres, United Nations high commissioner for refugees, said in announcing the new number in a joint statement with Lebanon’s minister of social affairs, Rachid Derbas. “The Lebanese people have shown striking generosity, but are struggling to cope.”

Mr. Derbas called the breached threshold of one million “an occasion to launch a humanitarian and political call under the title: ‘Lebanon should not be left alone.' ”

Government and United Nations officials have said they believe that the actual number of Syrians in Lebanon because of the conflict is much higher, because many do not register their presence.

This influx has overwhelmed public services, damaged the economy and raised fears that the same sectarian and political splits fueling the war in Syria could lead to greater violence here. Already, gunfights between neighborhoods that support opposite sides in the war are routine in the northern city of Tripoli, and a series of car bombs believed to be linked to the Syrian conflict has killed dozens of civilians.

Unlike some of Syria’s other neighbors, Lebanon has not built camps for refugees, leaving them to search for accommodations in host communities, often in unfinished buildings, storerooms or animal sheds. This has created tensions with the Lebanese, who often see the Syrians as a drain on resources.

Half of the refugees in Lebanon are under 18, and only a quarter of the 400,000 school-age refugee children are in school.

Reflecting the desperation of many refugees, a Syrian mother of four who fled Syria two years ago set herself on fire after her aid was cut, according to a United Nations official cited by Reuters. And a video that circulated online on Thursday showed a Syrian man committing suicide by leaping from the roof of an apartment building after losing his job.

To handle the crisis, the Lebanese government, the United Nations and other aid agencies say they need $1.89 billion for 2014 and that only a fraction of that amount has been given so far.
